Abstract: ABSTRACT This invention relates, in one of its aspects, to a process for the preparation of ortho-methyl anilines from ortho-amino benzyl sulfoxides. An ortho-amino benzyl sulfoxide is converted to an ortho-amino benzyl halide by reaction with a nonoxidizing acid halide and is converted to a stable quaternary salt by reaction with a tertiary amine preferably in the presence of an alcohol. The quaternary salt may be cleaved by hydrogenation to form ortho-methyl anilines. Other aspects of the invention relate to novel intermediate quaternary salts and to a process for forming those quaternary salts.

Abstract: Abstract Fuel injection apparatus for an engine includes two intake tubes each having a throttle valve, a fuel injection valve for injecting fuel into each of the intake tubes, a hot-wire air flowmeter for measuring the quantity of intake air sucked into the intake tubes and a by-pass passage accommodating the detection portion of the flowmeter. The by-pass passage has an inlet portion for introducing the static pressure of air flow sucked into each intake tube, a central portion for passing the air introduced from each intake tube and an outlet portion for discharging into each intake tube the air passing through the central portion.  The detection portion of the flowmeter is located in the central portion of the by-pass passage.  In this way the flowmeter is able to obtain an output relatively undisturbed by air pulsations to obtain improved performance and fuel consumption.

Abstract: ABSTRACT OF THE DISCLOSURE:       A two-speed power transmission having a gear box in which are mounted, for rotation about parallel axes, a power input shaft, an intermediate shaft and an output shaft.  A first gear train interconnects the input and the intermediate shafts for driving the intermediate shaft into rotation.  Within the gear box are also second and third gear trains, each having a first gear secured on the intermediate shaft for rotation therewith and a second gear in mesh with the first gear, these second gears being freely mounted on the output shaft so as to rotate independently, the second and third gear trains having different diameter ratios.  A drive wheel is mounted on the output shaft, between the second gears, for rotation with it and for slidable displacement over it.  The drive wheel and the second gears are provided with meshing parts permitting the drive wheel to mesh selectively with one of the two second gears to bring the output shaft into rotation.  The space between the two second gears is sufficient to allow for a neutral position of the drive wheel and the latter is shifted toward either one of the two second gears by means of a manually operable oscillating shifting stirrup member.
